A Cisco router can have multiple connections to networks. These connections are known as interfaces for Cisco Routers. For naming each interface, Cisco generally uses the type of interface as part of the name. Which of the following are true about the naming conventions of Cisco Router interfaces?
Each correct answer represents a complete solution. Choose all that apply.
A Cisco router can have multiple connections to networks. These connections are known as interfaces for Cisco Routers. For naming each interface, Cisco generally uses the type of interface as part of the name.
Following are some of the naming conventions of Cisco Router interfaces:
An Ethernet interface that is fast always starts with an F.
An interface connected to a serial connection always starts with an S.
An interface connected to an Ethernet segment of the network always starts with an E.
An interface connected to a Token Ring segment always starts with To.
Which of the following are the countermeasures against WEP cracking?
Each correct answer represents a part of the solution. Choose all that apply.
A user can use some countermeasures to prevent WEP cracking. Although WEP is least secure, it should not be used. However, a user can
use the following methods to mitigate WEP cracking:
Use a non-obvious key.
Use the longest key supported by hardware.
Change keys often.
Use WEP in combination with other security features, such as rapid WEP key rotation and dynamic keying using 802.1x.
Consider WEP a deterrent, not a guarantee.
Answer D is incorrect. SSID stands for Service Set Identifier. It is used to identify a wireless network. SSIDs are case sensitive text
strings and have a maximum length of 32 characters. All wireless devices on a wireless network must have the same SSID in order to
communicate with each other.
The SSID on computers and the devices in WLAN can be set manually and automatically. Configuring the same SSID as that of the other
Wireless Access Points (WAPs) of other networks will create a conflict.
A network administrator often uses a public SSID that is set on the access point. The access point broadcasts SSID to all wireless devices
within its range. Some newer wireless access points have the ability to disable the automatic SSID broadcast feature in order to improve
network security.
What does a firewall check to prevent certain ports and applications from getting the packets into an Enterprise?
A firewall stops delivery of packets that are not marked safe by the Network Administrator. It checks the transport layer port numbers and the
application layer headers to prevent certain ports and applications from getting the packets into an Enterprise.
Answer C, A, and D are incorrect. These information are not checked by a firewall.
Which of the following statements about system hardening are true?
Each correct answer represents a complete solution. Choose two.
System hardening is a term used for securing an operating system. It can be achieved by installing the latest service packs, removing unused
protocols and services, and limiting the number of users with administrative privileges.
You work as a Network Administrator for Net Perfect Inc. The company has a Windows Server 2008 network environment. The network is configured as a Windows Active Directory-based single forest network. You configure a new Windows Server 2008 server in the network. The new server is not yet linked to Active Directory. You are required to accomplish the following tasks:
Add a new group named "Sales". Copy the "Returns" group from the older server to the new one.
Rename the "Returns" group to "Revenue". View all group members, including for multiple groups/entire domain.
You use Hyena to simplify and centralize all of these tasks. Which of the assigned tasks will you be able to accomplish?
Each correct answer represents a complete solution. Choose all that apply.
Hyena supports the following group management functions:
Full group administration such as add, modify, delete, and copy
Rename groups
Copy groups from one computer to another
View both direct and indirect (nested) group members for one or more groups [only for Active Directory]
View all group members, including for multiple groups/entire domain [only for Active Directory]
Answer D is incorrect. All group members can neither be viewed nor managed until the new server is linked to Active Directory.
